President Donald Trump had a "fiery" phone call with Denmark's Prime Minister last week, putting the NATO ally into "crisis mode," the Financial Times reported, citing officials briefed on the matter. European officials told the FT the call did not go well and that Trump was aggressive and confrontational with his Danish counterpart. Newsweek reached out to the White House for comment Friday afternoon via email. Danish Prime Minister Mette Frederiksen's office said it "does not recognise the interpretation of the conversation given by anonymous sources" and pointed Newsweek to Frederiksen's official press release detailing the phone call.
